>I just made a 4 x 24 TB ZFS pool How much RAM did you install? Did you follow the 1GB per 1TB recommendation for ZFS? (i.e. 96GB of RAM)
Some myths never die, I guess..
Integrating a dust filter (not necessarily HEPA, but MERV 11) and the required fan upgrades would be wonderful.

I wouldn't say that being new is an absolute requirement. I recently upgraded my ZFS pool from SATA to SAS HDDs. Since SAS HDDs have much better firmware for early error detection and monitoring, I decided to buy 50% refurbished. Even if I lost half of them, I would still be safe. I also have offsite backups. This setup worked really well for me, and I feel completely confident that my data is safe while not wasting…
So you buy used enterprise disks because their error detection is 'better'? Do you have any source for this claim? Why would be the firmware so different? Software is cheap i don't think they would be that different. I mean a used enterprise disk gets sold after it was running on heavy load for a long time. Any consumer hdd will have a lot less runtime than enterprise disks.
Wait. You build a new one every -year-?! How does one establish the reliability of the hardware (particularly the aliexpress motherboard), not to mention data retention, if its maximum life expectancy is 365 days?
Somebody else shared this, but I'm the blog's author. I think you're asking good questions, but they're not from the point-of-view of the people who actually benefit from these blogs. I've answered the "You build one every year?" question quite a few times over the years. These blogs have a shelf life. After about a year, newer hardware is available that's a better a better value. And after 2-3 years, it starts to ge…
That's true of course. The problem, in my view, is that this is how everyone on the internet acts especially the "reviewers" or "builders" or "DIYers". It's not just you, so don't take this as a personal attack.
Almost all articles and videos about tech (and other things now too) do the equivalent of "unboxing review". When it's not strictly an unboxing, it's usually like "I've had this phone/laptop/GPU/backpack/sprinkling system/etc for a month, and here is my review"
I stopped putting much weight on online reviews and guides because of that. Almost everyone who does them uses whatever they are advertising for _maybe_ a month and moves on to the next thing. Even if I'm looking for an older thing all reviews are from the month (or even day) it was released and there is very little to non a year or 2 after because understandably they don't get views/clicks. Even when there are later reviews, they are in the bucket of "This thing is 3 years old now. Is it still worth it in 2025? I bought a new one to review and used it for a month"
Not to mention that when reviewers DO face a problem, they contact the company, get a replacement and just carry on. Assuming everyone will be in the same position. From their prospective, it's understandable. They can't make a review saying "Welp, we got a defective one. nothing to see here". On the other hand, if half the reviewer faced problems, and documented it, then maybe the pattern will be clearer.
Yes, every reviewer is a "one guy on the internet" and "is--and always will be-- an anecdote". No one is asking every reviewer to be come Consumer Reports and test hundreds of models and collect user feedback to establish reliability scores. But at the same time if each did something similar it would be a lot more useful than what they do.
I'll give you a concrete example off the top of my mind --a Thermapen from ThermoWorks.
When I was looking for "the best kitchen thermometer" the Thermapen was the top result/review everywhere. Its accuracy, speed and build quality were all things every review outlined. It was a couple of years old by then and all the reviews were from 2 years ago. I got one and 6-8 months later, it started developing cracks all over the body. A search online then showed that this is actually a very common issue with Thermapens. You can contact them and they might send you another one of the older models if they still have them (they didn't in my case) but it'll also crack again. Maybe you can buy the new one?
May sound petty to put that one example on the spotlight, but very similar thing happened to me with a Pixel 4, a Thinkpad P2, a Sony wireless headphones, a Bose speaker, and many more that I'm forgetting. All had stellar "3 week use reviews". After 6 months to a year and they all broke down in various ways. Then it becomes very easy to know what to search for and the problems are "yeah, that just always happens with this thing"

Agree, but that's taking a risk with your data (whereas if a MB fails, you likely just need to replace it but your data is fine), and HDD kind of have a finite number of hours in them. Where buying them used I think makes sense is for a backup server, that you leave off except the few hours in a week where you do an incremental backup. Then it doesn't really matter that the drives have already been running for 3 or 4…

I can confirm that the Odroid H4 Plus also supports in-band ECC. If I remember right, Memtest86 showed different stats when I ran it with in-band ECC enabled/disabled though I didn't have a good way to test that an error was actually corrected.
Some systems allow forcing an ECC error, but assuming that's not available, if you can adjust memory voltages or timings, you can usually encourage errors that way and confirm memtest detects ECC corrections.
Only when they expose this feature in Linux EDAC drivers it becomes possible to do this. In the past Intel had maintained well its Linux EDAC drivers, but AMD had frequently great delays between the launch of a CPU and the update of the drivers. After the many lay-offs at Intel, it is unknown whether in the future their Linux support will remain as good as in the past.
In this economy?
Very sad that HDDs, SSDs, and RAM are all increasing in price now, but I just made a 4 x 24 TB ZFS pool with Seagate Barracudas on sale at $10 / TB [1]. This seems like a pretty decent price even though the Barracudas are rated for 2400 hours per year [2] but this is the same spec that the refurbished Exos drives are rated for. By the way, interesting to see that OP has no qualms about buying cheap Chinese motherboar…
I built the case from Makerbeam and printed panels, an old Corsair SF600 and a 4 year old ITX system with one of Silverstone's backplanes. They make up to 5 drives in a 3x5-1/4 bay form factor. It's a little overpowered (a 5950X), but I also use it as a generic server at home and run a shared ZFS pool with 2x mirrored vdevs. Even with inefficient space it's more than I need. I put in a 1080ti for transcoding or odd jobs that need a little CUDA (like photo tagging). Runs ResNet50-class models easily enough. I also wondered about treating it as a single-node SLURM server.

How else is one to get the clicks?
Plus the commission from the undisclosed Amazon affiliate links in the post. They're tagged for the post and year so must be worth it to go to that trouble rather then using generic tag for the whole blog. tag=diyans2024-20, tag=diynas2025-20,tag=diynas2026-20
It doesn't increase the price or impact your buyer experience in any way, so why do you care? If this blog post introduced you to a product you wanted to buy, why should you have a problem with the author getting a finders fee from the seller? Just seems mean-spirited.
